The latter has a more angular anterior edge than that of S. tiburo , and bears lobes on its posterior edges, leading to it being described as "shovel-like". [ 1 ]
Carcharhinus sealei found in Malaysia, its similar markings on the second dorsal fin cause its morphological identification to overlap with C. tjutjot.
